Description
Technical Field
The invention relates to the field of graphic processing, in particular to a method and a device for determining a maximum inscribed circle of a closed graph in a vector diagram and electronic equipment.
Background
The color filling game is a game in which the color is filled in the area of a specified closed figure, so that a complete picture consisting of more than one closed figure (the picture is a scalable vector diagram, commonly called SVG (scalable vector graphics) and is characterized in that the picture cannot lose definition after being arbitrarily enlarged and reduced) is changed into a color picture from a black and white line diagram.
In early color-filling games, each closed figure in the whole vector diagram is independent, and players need to click and color each closed figure one by one. In the newly appeared color filling game, all closed graphs are grouped in advance, and the colors corresponding to the closed graphs in the same group are consistent; for example, if the subject of a picture is a owl, the closed figures that make up the pattern of the owl are divided into four groups: dividing each closed graph corresponding to the head feather of the owl into a group, and presetting the color corresponding to the closed graph of the group as dark brown; dividing all closed graphs corresponding to the abdomen of the owl into a group, and presetting the color corresponding to the closed graphs of the group as light yellow; dividing each closed graph corresponding to the back of the owl into a group, and presetting the color corresponding to the closed graph of the group as light brown; dividing each closed figure corresponding to the tail of the owl into a group, and presetting the color corresponding to the closed figure of the group as black; when the player clicks the closed graph corresponding to the owl head feather, the closed graph clicked by the player is filled with dark brown.
To let the player know which closed figures belong to the same group, the group of closed figures needs to be indicated in the form of a mark inside the closed figures. Because the shapes and sizes of the closed figures are different, if the display of each mark is maximized, the center coordinates and the radius values of the maximum inscribed circle of the closed figure are calculated firstly, and then the mark is arranged in the maximum inscribed circle.
At present, most of methods for calculating the maximum inscribed circle of each closed graph in a vector diagram convert an SVG picture into a portable network diagram (PNG), and then process the PNG by using a computer vision method in computer graphics and OpenCV. However, this method is not only slow when facing a picture containing hundreds or even thousands of closed figures, but also has very complicated computation logic and very low efficiency when encountering closed figures with "holes" (closed figures with "holes" refer to blank regions such as circles inside the closed figures).

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In a first aspect, embodiments of the present invention provide a method for determining a maximum inscribed circle in a vector diagram, which can improve efficiency of determining the maximum inscribed circle in the vector diagram.
Fig. 1 is a schematic flow chart of a method for determining a maximum inscribed circle in a vector diagram according to an embodiment of the present invention, as shown in fig. 1, the method according to this embodiment may include:
in this step, the source vector diagram (SVG picture) includes two main labels: a group tag (g-tag) and a path tag (path-tag) nested within the group tag in the form of a document tree. The group labels represent closed graph groups formed by grouping closed graphs in the source vector diagram, and the path labels represent paths of the closed graphs. The source vector diagram may include more than one group tag (i.e., each closed figure in the source vector diagram is divided into more than one closed figure group), and each group tag may include one path tag (i.e., the closed figure group represented by the group tag only includes one closed figure) or may include multiple path tags (i.e., the closed figure group represented by the group tag includes multiple closed figures).
In this embodiment, an attribute value is stored in the first group of tags, where the attribute value records the state of the tag, and the attribute value may include a color, and at this time, the filling color of the closed graph corresponding to each path tag in the first group of tags is consistent with the color attribute value of the first group of tags, that is, the filling color of the closed graph corresponding to the path tag in the same group of tags is the same; the attribute values can also comprise id, displacement and scaling, and when the source vector diagram is analyzed, the source vector diagram can be properly reduced based on the position value and the scaling value in the attribute, so that the calculation amount for determining the maximum inscribed circle of the closed graph in the subsequent steps can be reduced.
Optionally, after the source vector diagram of the color filling game is analyzed, a color value can be extracted according to the attributes of the first group of tags; judging whether the extracted color value is a white or black color value; if the extracted color value is a white or black color value, the closed graph corresponding to the path label in the first group of labels may be a background graph, and does not need to be filled by a player, and at this time, the closed graph represented by each path label included in the first group of labels may be ignored, and the maximum inscribed circle of the closed graph corresponding to the path label in the group of labels does not need to be determined.
in this step, an attribute value is stored in the first path label, where the attribute value may include a d (data) attribute, and the path data of the first path label is stored in the d attribute of the first path label. At this time, the extracting path data of the first path label in the first group of labels may include: acquiring a first path label in the first group of labels according to the first group of labels; and extracting the path data of the first path label from the attribute of the first path label.
Optionally, the attribute value of the path label may further include a color attribute, and at this time, the filling color of the closed graph corresponding to each path label may be separately set.
103, determining a circumscribed polygon of the closed graph represented by the first path label according to the path data of the first path label;
in this step, the circumscribed polygon is used to represent the frame of the closed graph, and the circumscribed polygon of the closed graph represented by the first path label may be determined by using a third party library svgpathools of Python.
104, carrying out mesh division on the external polygon according to an initial preset multiplying power;
in this step, when a mesh partitioning (meshing) process is performed on a polygon, the initial predetermined magnification directly affects the calculation accuracy and the calculation scale of the maximum inscribed circle determined in the subsequent steps, generally speaking, the larger the initial predetermined magnification is, the better the calculation accuracy is, but the calculation scale is increased, so that two factors should be balanced and considered comprehensively when the initial predetermined magnification is determined.
Optionally, the minimum x value, the maximum x value, the minimum y value, and the maximum y value of the closed graph represented by the first path label may be obtained according to the path data of the first path label, then the circumscribed rectangle of the closed graph is obtained according to the four values, and then the circumscribed rectangle is subjected to mesh division, so that the initial predetermined magnification is set conveniently. Alternatively, the value of the initial predetermined magnification may be set to 10.
Optionally, the circumscribed rectangle may be subjected to meshing by using a third-party library Pandas vectorization propagation calculation (vectorization propagation calculation, that is, the same task is performed on the same data column) of Python, and as the speed of performing such task by Pandas is extremely fast, the efficiency of meshing can be improved.
105, determining each inscribed circle of the closed graph by taking each grid division point in the closed graph as a circle center;
in this step, a third-party library shape of Python may be used to determine whether each mesh division point is located in an external polygon corresponding to the closed graph, and the mesh division point located in the external polygon is used as a mesh division point inside the closed graph.
Optionally, the determining each inscribed circle of the closed graph by taking each grid division point inside the closed graph as a circle center may include: drawing N circles by taking a first grid division point in the closed graph as a circle center and taking the 1 st to Nth step length radiuses as radiuses, wherein N is a natural number greater than or equal to 1; and if part of the locus of the Nth circle is positioned outside the closed graph represented by the first path label and all loci of the (N-1) th circle are positioned inside the closed graph represented by the first path label, determining that the (N-1) th circle is a first inscribed circle of the closed graph.
And 106, taking the inscribed circle with the largest radius in all inscribed circles of the closed graph as the largest inscribed circle of the closed graph.
In this step, the radii of the inscribed circles of the closed graph are compared, and the inscribed circle with the largest radius is used as the largest inscribed circle of the closed graph. If the maximum inscribed circle of the closed graph is not determined after the circumscribed polygon is subjected to the meshing processing according to the initial preset multiplying power (when the closed graph is too small, the value of the step radius may be larger than the radius of the maximum inscribed circle of the closed graph, or no mesh dividing point exists inside the closed graph, at this time, the maximum inscribed circle of the closed graph cannot be determined according to the methods in step 105 and step 106), the initial preset multiplying power may be adjusted according to a preset rule, where the adjusted multiplying power is larger than the initial preset multiplying power, for example: the adjusted multiplying power is twice of the initial preset multiplying power; carrying out meshing processing on the external polygon again according to the adjusted multiplying power; then, by taking each new grid division point in the closed graph as a circle center, re-determining each inscribed circle of the closed graph; and taking the inscribed circle with the largest radius in the inscribed circles of the re-determined closed graphs as the largest inscribed circle of the closed graphs.
Optionally, after adjusting the initial predetermined magnification for M (M is a natural number greater than or equal to 1) times, if the maximum inscribed circle of the closed graph is still not determined according to the magnification adjusted for the M time, it may be determined that the area of the closed graph is too small, and for the color-filling game, the closed graph with too small area may be ignored.
Optionally, the method described in steps 101 to 106 may be utilized to sequentially determine the maximum inscribed circle of each closed graph in the source vector diagram, and of course, the parallel computing capability of the computer may also be fully utilized, and the maximum inscribed circle of each closed graph in the source vector diagram is computed simultaneously by using multiple processes, so that the efficiency of determining the maximum inscribed circle of each closed graph in the vector diagram can be further improved.
Optionally, after obtaining the maximum inscribed circle of each closed graph, a group (group label) to which the closed graph belongs may be marked in the maximum inscribed circle of the closed graph. At this time, a closed figure with a too small maximum inscribed circle may exist in the source vector diagram, and the meaning of coloring the closed figure is not great for the color filling game, so after the maximum inscribed circle radius of the closed figure is determined, it may also be determined whether the radius of the maximum inscribed circle of the closed figure is smaller than a predetermined threshold, for example: the value of the preset threshold is set to 0.005 pixels, and if the value is less than the preset threshold, the closed figure can be ignored.
Optionally, after determining the maximum inscribed circle of each closed figure in the source vector diagram, a configuration file may be generated according to the source vector diagram and the circle center coordinates and the radius of the maximum inscribed circle of each closed figure in the source vector diagram, where the configuration file includes the path data ID of each path label, the color value, the circle center coordinates and the radius of the circle to be marked, the circle center of the circle to be marked coincides with the circle center of the maximum inscribed circle of the corresponding closed figure, and the radius is less than or equal to the radius of the maximum inscribed circle of the corresponding closed figure. For example: the radius of the circle to be marked is 60% of the maximum inscribed circle radius of the corresponding closed graph, so that when the mark is marked in the circle determined according to the circle center coordinate and the radius stored in the configuration file, the marked mark can be ensured to be positioned in the closed graph.
Optionally, when outputting the new vector diagram, the ignored closed graphics may be deleted from the source vector diagram, and a new vector diagram is generated.
Optionally, the new vector image may be loaded in a screen of the electronic device; and according to the circle center coordinate and the radius in the configuration file, numbers and/or letters are marked in the circle determined by the circle center coordinate and the radius. For example: and marking numbers and/or letters on the circle center, and controlling the sizes of the numbers and/or letters according to the radius. Optionally, a closed graph corresponding to the path label belonging to the first group of labels is labeled with a number 1, a closed graph corresponding to the path label belonging to the second group of labels is labeled with a number 2, and so on. Therefore, the player can conveniently know which closed graphics have the same color when playing the game.
Optionally, a game progress display area may be displayed in a partial area of the screen, where numbers and/or letters corresponding to numbers and/or letters marked in the closed graphics of the new vector diagram are displayed in the game progress display area, and each number or letter corresponds to a progress bar; when a user clicks the closed graph of the new vector diagram, receiving the clicking operation of the closed graph of the vector diagram; determining a closed graph corresponding to the clicking operation; filling corresponding colors in the click-operated closed graph according to the color values in the attributes of the group label to which the path label corresponding to the closed graph belongs, and displaying the current filling progress in a progress bar corresponding to the click-operated number or letter in a game progress display area. Therefore, the user can know the filling progress of the group of closed graphs according to the current filling progress displayed in the progress bar; the progress of the whole game can be obtained according to all the progress bars in the whole game progress display area.
The method for determining the maximum inscribed circle of the closed graph in the vector diagram provided by the embodiment can be used for analyzing a source vector diagram and acquiring a first group of labels in the source vector diagram; extracting path data for a first path label within the first set of labels; determining a circumscribed polygon of the closed graph represented by the first path label according to the path data of the first path label; carrying out mesh division on the external polygon according to an initial preset multiplying power; determining each inscribed circle of the closed graph by taking each grid division point in the closed graph as a circle center; and taking the inscribed circle with the largest radius in all inscribed circles of the closed graph as the largest inscribed circle of the closed graph.
